I recently had the fuel pump as well as the cam replaced on my car because it was losing power at higher speeds. All seemed fine until it happen again a couple times but at way to fast for me to have to go back to audi again. So I replaced the diverter valve thinking that it was just a boost problem, that made it better but it happened again after installing the oem d valve. I was talking to my dealer and he said it is possible that giac chip simply creates problems with the cam, could it be possible that cam problems would come back after less than two week? Has anyone else had this problem with the giac chip?
Thanks for the help

 

no problems with GIAC-X for about 5k miles so far
